We welcome single piece and production cut-to-length orders. We can provide heat treating, machining, and testing.

ASTM B163 Nickel 201 Seamless Tube Specification

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications.

Product Name: ASTM B163 Nickel 201 Seamless Tube

Our specialized process for seamless tubing manufacturing begins with either an extruded hollow tube or a solid bar drilled to our exacting specifications. The material is then reduced in size a number of times through various cold working techniques until it reaches the specific size, tolerances, and temper required by our customer. After each cold working cycle the tubes are cut, cleaned and heat treated in preparation for the next cold working step. Seamless tubes can be created in a variety of different sizes and shapes from a wide range of alloys.

Corrosion resistant nickel alloys are ideal for tubes used in some of the most demanding applications

At Piyush Steel we export & supply precision tubes using stainless steel, nickel, titanium and zirconium alloys, in a whole range of sizes and cross section shapes to suit your requirements. Both our seamless and welded products come both as straight lengths of tubing or in coils.

Our seamless and welded drawn tubes range in size from under 0.010” (1/4 mm) right up to 1.5” (38.1mm) outside diameter, and we can produce finished wall thicknesses down to less than 0.002” (0.05 mm) through to 0.150” (3.8mm).

You can order straight lengths of tubing from us up to 45ft (14m) long or coiled tubes up to 3,200ft (975m) in length.

High temperature nickel based alloys

A further increase of specific alloy elements (such as chrome, molybdenum, tungsten, titanium, aluminium, niobium, etc.) improves the high temperature, high strength characteristics of austenitic steels. The disadvantage of austenitic stainless steels occurs in the fact that these elements have a reduced solubility. In order to compensate this effect and to reach the desired result, the nickel concentration can be increased. The highest alloyed types of high temperature nickel based alloys contain only a very low iron concentration.

Characteristics

Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.

Outstanding resistance to caustic alkalis up to and including the molten state.

In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidising salt solutions severe attack will occur.

Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to 550C.

Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in de-aerated acid.

Virtually immune to inter granular attack above 315C, chlorates must be kept to a minimum.
